ASN and BGP organisation lookup

BGP and organisation data from ASN, IP or prefix.

Queries leave from this Linux server, not your ISP DNS. Free. Cached answers can differ for a short time.

An ASN is an operator’s identity in BGP. Team Cymru whois maps IP to AS; RIPEstat fills in summary data.

Useful for hosting vs ISP vs CDN when filing abuse. Prefix ownership should still be confirmed in whois.

Which AS originates a prefix is visible in BGP; more-specifics can move to another AS. Abuse mail is a separate whois field.

Frequently asked questions

What is AS15169?

Google. 1.1.1.1 is Cloudflare (AS13335); 8.8.8.8 is Google.

ASN vs IP?

ASN is the operator identity; an IP is one address they announce.

RIPE, ARIN, APNIC?

Regional internet registries. RIPEstat is Europe-heavy; other RIRs show up in whois.

Does anycast confuse AS?

Yes. 1.1.1.1 is Cloudflare AS13335, but packets go to the nearest PoP.

What is prefix hijack?

An unauthorised AS announcing your prefix. This tool is not a live BGP feed; RPKI/IRR are separate.
